although these worksheets are helpful, number 8 makes no sense and number 9’s answer should be corrected as the answer is wrong. solving it myself, my answer makes sense, but, sorry to say, yours does not make any sense at all.

Hello there, sir. I’m a student and I found your balancing worksheets great. However, in this particular sheet, you got #2 incorrectly. The answer key had 2, 7, 2 and 6 coefficients respectively, which makes 2 carbons on the reactant and 6 on the product. The correct coefficients would be 1, 2, 1 and 2, respectively.
